The UK's first 4G network is set to be launched this morning by telecoms firm Everything Everywhere.
Last month, media regulator Ofcom granted permission for the mobile broadband provider to launch fourth-generation services using its spare 1,800MHz spectrum.
The move has riled a number of other network operators - who are waiting for Ofcom to auction off space in the 800MHz and 2.6GHz bands - and led to threats of legal action.
But despite government intervention reportedly securing a truce, Everything Everywhere is set to press ahead with the soft launch of its 4G service portfolio.
A new brand is expected to be unveiled at the launch event today (Tuesday September 11th), which will be charged with bringing the benefits of next-generation mobile services to UK businesses and consumers.
Among the expected benefits of 4G will be faster broadband speeds, increased network reliability and wider coverage.
